MMM-Spotify

Hmmm weird. It seems nothing special suspicious point at all.
The only thing I suspect is that you are using different account on MMM-Spotify and your real spotify player. but i think it would have bare chance.
Try onStart to activate it by force, at least it would show some errors.

Even if wasn’t the token OK at MM loading log?

Token might be OK with different account, but if different account is used, it cannot derive current playback info. (You cannot get spotify info from your friend’s account playback with your account). Have you several accounts for spotify?

This is normal. Unless you should customize CSS, with no playback, the module will be disappeared by default. (Some PPL have wanted so I added that feature.)
When playing on any Spotify player starts, module will be appeared. (If it can get current playback info from server)
